Hello, so i just got my S2 license, but i have this problem on all the multiplayer servers i go to.

all the player icons on the minimap are just in the pit area, even when my friend is driving i just see his icon on the pit area, and the car bodies are invisible for me. I can't see anyone nor they can see me. i have tried turning off firewall, installing dx9, .net framework (all this was suggested but ingame players)

For me it sounds as a heavy internet lag problem

Try to open the connection list (pres N key) ant click the UDP button to switch to TCP mode.

Your ISP may be blocking UDP traffic on your connection, failing to detect LFS needs those packets.
